FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
chaeta & mesothoracic tergum | somatic clone
Homozygous clones in the wing result in a crumpled wing blade. Ectopic wing veins are present, in particular near veins L2, L3 and the anterior crossvein, sometimes concomitant with an incomplete posterior crossvein.
Homozygous clones in the notum can result in the loss of bristles, a grossly reduced scutellum, or loss of the entire hemi-notum.
